Hi all,

If anyone speaks swedish then this site may be useful

http://www.svenskakemi.nu/

This is the page they have put up in english.

http://www.svenskakemi.nu/indexUK.html

They might be worth a go. Looks like they sell german dark and some other pyro aluminium. From what i can understands on the chemicals page.

Edit,

If anyone does read swedish could you give me any info about the products they sell. A translation of the products page would be very useful. If we know the chemicals they actually sell then they say they can receive emails in english.

I don't speak Swedish but most of the chems are fairly easy to interpret, if not look at the formula. They say they ship to the UK but I am yet to contact them mainly due to a lack of cash. They do seem reasonably priced on some things but not others. Here are some of the more interesting ones (rough exchange rate):

NH4CLO4 8KG ?162
KCLO4 5KG ?115
Ba(CLO3)2 5KG ?139
Mg 500g ?25, 3KG ?108
Ba(NO3)2 4KG ?73
Sr(NO3)2 4KG ?75
C2Cl6 750g ?13
Ti 1KG ?35
MgAl 500g ?24
Dark Al 5KG ?160

Also some tubes 26.5mm ID 6mm wall 180mm long 50 for ?10

Has anyone had any oxidisers shipped from this company before? If so were the shipping costs like?

They are very good.. But you have to add 25% VAT on top of there prices + You may find they will only take largish orders...I found them very helpfull..they dont take credit card...you have to pay direct into there bank which i find a pain to do...never get the time to go to the bank... ..

The shipping cost were reasonable...a 12kg order cost about 450 SEK which is about ?42 that includes 25% vat..Delivery takes about `1 week barring no hold ups at customs

I've also had some contact with Hans, but never ordered from him. The shipping costs will allways be 40 euro's or more, even if you make an order of one kg.

He told me that customs do not interfere with shipments inside the EU and that he has shipped perchlorates to almost every European country.

They are building a new, English online shop as we speak. It will probably be up the 1st of may. The prices should go down a bit too and they will be going to accept other methods for payment.

I have mentioned this site before here in this forum but, I can't seem to find my old post.

Thy are very good and, I have never had any problems when ordering!
But as mentioned, small orders don't pay of. When you order, you have to order "a lot" (or many things) for it to be worth it if you order from abroad. And for international orders you have to order over a price limit. (I don't remember for sure how much).
Don't hesitate to e-mail them and ask! Mostly they answer you mail fast.

Worth noting is that some chemicals marken "slut" means they are out of stock. If enought people asks about the chemical, they will buy new to have in stock.
And "I lager i februari" means "in stock in february".
And to the question if I can translate SWE, I answer "yes I can".

(1 euro = 9 SEK; 1? = 13 SEK)

I got my first bag of KNO3 off ebay... Cost me ?5.50 for 500g!

who was that from? sounds a bit steep!

[karlfoxman]

i am thinking of getting some chemicals from timstar, what sort of questions will i be asked and will i need to send off ID to get them? i am looking at getting potassium chlorate and magnesium powder to start with. has anyone ordered from them?

[Richard H]

You will probably need a business account to order from a lab supplier. When it comes to being asked questions, honesty is the best policy.

[karlfoxman]

thanks richard will try my best to get hold of the stuff, i have some nice 4 inch red pill box shells in the pipe line.

[broadsword]

You may find it quite hard to get chemicals from them! Others on this forum have had no replys and have been totally ignored!

[lord_dranack]

I buy most of my chemicals from them, as they are one of the cheapest lab suppliers around.
When I first ordered from them, they asked about what background I had in chemistry- I assume to know they were not selling dangerous chemicals to just anyone!
The guy knew exactly what I wanted the chemicals for, and was quite helpful.

[karlfoxman]

so its best to tell them what i will really do with them? looks like i will have to drop them a line soon to check it out, they are cheap and sell quite alot of stuff. looks like for the time being i am stuck with 4inch willow shells. oh and if anyone is needing mortars fairly cheap the www.essextubes.co.uk 2 x 100mm mortars cost me ?22 + vat.

[Richard H]

?22 for a couple of 4" tubes? ouch Better off buying in bulk...

[karlfoxman]

is that really expensive? i was gonna buy lots of sizes but only making 4inch shells at the moment. does anyone use 'fimo' as pvc here? is it easy to mix, i have found a good blue star source but need ammonium perchlorate? anyone know where i can get this?

May as well add my post from the other forum that shall remain nameless:

A note on substuting KClO3 for KClO4:

If you want the oxygen balance to remain the same you must compensate for the lower oxygen density of KClO3.  KClO4 is about 46.9% Oxygen, KClO3 is only 39.2% Oxygen.  Therefore you should use 1.196 times as much.

In Chaz's original composition that means using 75 KClO3 instead of 63 KClO4.

Of course that adds a little more KCl to the flame which has a cooling effect, but I doubt that is very significant in a blue composition.

Also note that using Copper Oxide in Chlorate compositions is ill-advised.  Copper ions sensitise Chlorates at the best of times, but metal oxides in particular have a catalytic effect on Chlorates.  This is probably one reason for their good burn rate, once you increase their oxidation you may find them too reactive.

Copper Carbonate would be a safer Cu ion donor.  1.553 times more Copper Carbonate than Copper Oxide will supply the same amount of Copper, or 20 parts instead of 13.  If you are using "Basic Copper Carbonate" use 1.591 times as much or about a half-part more than 20 parts.  The extra waste CO2 and H2O will consume energy from the flame so increasing the oxidiser and fuel a little can compensate if the burn rate is affected too much.

As Chlorate cut stars with Copper in them they very probably don't require any priming at all.
